Description
Technical field
The present invention relates to a kind of development mechanism.Specifically, be a kind of light-duty energy storage type rapid deployment mechanism.
Background technology
This mechanism is applicable to aerospace field, as the bullet of kinetic energy weapon.Its objective is for bumped against by target of attack before launch rapidly, thereby increase lethal area.
What twine on the bullet of U.S.'s space-based kinetic interception guided missile is umbrella frame shape steel disc, launches performance though guaranteed good elasticity, and quality can be very big, thereby increased the launch cost of guided missile.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, light, development rate is exceedingly fast, launch the high light-duty energy storage type rapid deployment of stability mechanism, this mechanism can reduce launch cost greatly under the prerequisite that guarantees lethality.
For achieving the above object, the present invention is further detailed explanation below in conjunction with Fig. 1 and Fig. 2.
Rapid deployment of the present invention mechanism is made up of disc matrix 1, the thin bar 2 of plurality of elastic, flexible cord 3, some beads 4 and cavity 5.One end of thin elastic rod 2 is fixedly connected on the Along ent of disc matrix 1 circumference; Flexible cord 3 fixedly ties up to the middle part and the end of every thin elastic rod 2; A bead 4 is all passed in the centre position of every section flexible cord 3; Thin elastic rod 2 can be wrapped on the matrix 1 under the effect of external force, and can be drawn in cavity 5 together with flexible cord 3 and bead 4.When drawing that part cavity 5 in along with disc matrix 1 relative motion takes place in and after from cavity 5, spinning off, thin elastic rod 2 can be in the extremely short time rapidly expansion stretch, and the flexible cord of each section 1 is stretching.Thereby the part of ejection plays interception function as a cobweb to target of attack, and 4 pairs of targets of attack of the bead on the cord 3 play destruction.Because bead 4 is hollow structures, when mechanism when drawing in cavity 5, the flexible cord 3 at place separately can be taken in the spherical shell, so, during mechanism deploying, flexible cord 3 can not take place to twine or be entangled with thin elastic rod 2, and behind the mechanism deploying, and each bead 4 all remains on the position of every section cord center fixed can play.
Certainly, the quantity of thin elastic rod, flexible rope and bead can suitably increase and evenly distribution, as long as can reach the development rate that needs, also thin elastic rod can be changed to the carbon fibre slice of high tenacity.Such conversion or layout all drop within protection scope of the present invention.

The 1-circular base plate, 2-thin elastic rod, the flexible cord of 3-, 4-bead, 5-confinement ring.
The specific embodiment
This rapid deployment mechanism relatively simple for structure mainly is made of following several parts:
1, circular base plate (mandrel): its structure is similar to the bobbin of " worker " font, the retaining at axle two ends along on have the aperture of circumference in equal parts, as shown in Figure 3.
2, thin elastic rod or elastic sheet (some): be characterized in having wilfulness and intensity preferably, under the effect of external force, can be curled into circle freely, and after removing external force constraint, can freely return to the straight-bar state with certain diameter.
3, cord (plurality of sections): play the effect that connects each thin elastic rod and tie down particle (prill).
But 4, hollow folding bead (some): function element.Have the aperture that allows cord to pass freely through, its inner space can hold the fine particle with certain mass and the cord of gathering.Its concrete folding can be thread forms also can be the buckle form.Fig. 4 shows the intention of opening with closed for it.
5, confinement ring: loop configuration is the accessory of rapid deployment mechanism.Its internal diameter is more bigger than the edge diameter of circular base plate, can easily be enclosed within on the circular base plate, as shown in Figure 5.
With six roots of sensation thin elastic rod is example, and the assembling of light-duty energy storage type rapid deployment mechanism is described below:
1, respectively that an end of thin elastic rod is evenly fixing along the tangential direction of circular base plate mandrel, as shown in Figure 6.
2, bolt in the middle of the plurality of sections there is the cord of metal particle tie up to the relevant position of thin elastic rod respectively, as shown in Figure 7.
More than two steps finished the main part of rapid deployment mechanism.Following step is that members such as thin elastic rod and cord are drawn in:
3, thin elastic rod is crimped onto in " worker " type groove around the circular base plate mandrel, and inserts the basal disc retaining along in the last corresponding aperture, as the interim constraint that prevents that thin bar from ejecting with pin.
4, after at first being accommodated in each section cord in the hollow bead, also they being collected in the circular base plate mandrel and be crimped onto in " worker " type groove.
5, confinement ring is enclosed within on the main part of drawing good rapid deployment mechanism in, as shown in Figure 8.
More than five steps finish the assembling of mechanism.
Or the fixed constraint ring, or fixing circular base plate, in a word, can keep can having between circular base plate and the confinement ring relative motion vertically to get final product.As shown in Figure 9, during work, rapidly confinement ring is come off, thereby the thin elastic rod that curls can discharge the elastic potential energy that stores in a short period of time, is launched into straight-bar, and their cord of stretching connection, form the network structure shown in Fig. 9 (3), play interception function.
